文摘A simulation method for the thermal analysis of InAlAs/InGaAs/InP mid-infrared quantum cascade lasers (QCLs) based on finite-element method (FEM) is presented. The thermal distribution of the QCLs on substrate-side or epilayer-side mounting forms is simulated and the results are compared. Results show that the epilayer-side mounting form has much better heat dissipation capability than the substrate-side mounting.
